Correct Answer: B

Explanation

If the ratio of the time it takes Sakshi and Tanya to complete the same task is 5:4,
and it takes Sakshi 20 days to complete the task,
then it will take Tanya 16 days to complete the task.
This is because Tanya is 25% more efficient than Sakshi,
and the ratio of their work rates can be expressed as 5:4,
with Tanya's work rate being 4/5 of Sakshi's work rate.
